Article Abstract

Copper (Cu) pollution resulting from human activities has emerged as a prominent issue stemming from industrial development. The entry of copper into the soil, either directly or through industrial wastewater, exerts adverse effects on plant growth, leading to its accumulation in significant quantities within the plant and subsequent endangerment of human health through the food chain. DCPTA [2-(3, 4-dichlorophenoxy) triethylamine] mitigates certain abiotic stresses, yet the precise mechanism by which it alleviates Cu-induced phytotoxicity remains unknown. This study has demonstrated that DCPTA reduces the impact of copper stress on plants by enhancing leaf pigment and photosynthesis, regulating root growth, and balancing the antioxidant system. Furthermore, the accumulation of Cu in leaves and roots of cucumber treated with DCPTA was significantly lower than that in seedlings treated with Cu alone. Transcriptome analysis showed that copper absorption, transport, detoxification genes, cell wall component related genes and nitrogen metabolism related genes played a crucial role. In conclusion, exogenous application of DCPTA can partially alleviate copper stress in cucumber.

Background: Insufficient evidence is available to confirm the effect of exposure to airborne metals on mental disorders, particularly among asthmatics. We aimed to investigate the effect of airborne metal exposure on mental health responses in asthmatics and the general population.

Methods: Using nationally representative cross-sectional data, a total of 47,796 adults were analyzed.

Trace elements (TEs) are essential for human health and for maintaining immune responses against potentially aggressive pathogens, such as the human immunodeficiency virus (HIV). During the infectious process, the body needs greater amounts of TEs in order to coordinate an efficient immune response to combat the invading agent, a condition that reflects in lymphocyte proliferation and activation of the antioxidant defense system of neutrophils and macrophages. Thus, during the progression phase of a viral infection, immunomodulation of TEs such as iron, zinc, chromium, magnesium, selenium, copper, calcium, and manganese occurs, can lead to immunosuppression and increased oxidative stress.
